      Determine your resting heart rate. Put a pad and pencil next to your bed. Take your pulse in the morning just after you wake up. Record this number for three days. The average of these numbers is your resting heart rate.

      Determine your maximum heart rate. There are several formulas available to do this. The most common formula for men is 220-(your age). For women, the formula is 206-(0.88 x age). Once you have this number, it is helpful to determine 70, 80 and 90 percent of your maximum heart rate for reference.

      Use a high-quality heart monitor while you play. A high-quality monitor will have protected frequencies to avoid interference with other players. Once you have input your information into the monitor, it will track the activity of your heart and determine how hard your body is working. It will then be able to display the number of calories burned.

      Use an online calculator if you are unable to use a heart monitor. There are many sites available. Look for one that allows you to input your specific data such as age, weight and fitness level; these will be more accurate than those that just use an average.
